Last year in the German city of Ulm, Daimler started up an experimental car-sharing system called car2go. It incorporated a fleet of 50 smart fortwos, that users could pick up in various locations, drive as long as they wanted, and then leave within the city. Ulm’s program is now up to 20,000 members and 200 cars, while a younger sister project in Austin, Texas, is up to 10,000 members. Given that success, Daimler has just announced a new “car2go edition” of the fortwo, designed specifically for use in the program. We got a look, at the 2010 Paris Motor Show.
